Bulletin of the IDF N° 514/2022: Inventory of microbial food cultures with safety demonstration in fermented food products
Since 2002, the International Dairy Federation (IDF), in collaboration with the European Food and Feed Cultures Association (EFFCA), has been conducting a project on the demonstration of the safety of microbial food cultures. The first inventory of food cultures was published in 2002 [14, 15], the scientific rationale for the inventory of microbial food cultures […]
Bulletin of the IDF N° 513/2021: Identification of Probiotics at the strain level – Guidance Document
Probiotics are specific microbial strains that have a beneficial effect on the health of the host and are defined as “Live microorganisms that, when administered in adequate amounts, confer a health benefit on the host”. In 2002, a joint FAO/WHO Expert Consultation on Evaluation of Health and Nutritional Properties of Probiotics in Food proposed the […]
ISO 24223 | IDF 253: 2021 Cheese – Guidance on sample preparation for physical and chemical testing
This document gives guidance on the sample preparation of fresh cheese, (semi) soft cheese, (semi) hard cheese, processed cheese and whey cheese for physical and chemical analysis, including analysis by applying instrumental methods. This document describes the (sub)sampling, and sample preparation steps carried out after sampling according to ISO 707 | IDF 50 and prior […]
ISO 23970 | IDF 252: 2021 – Milk, milk products and infant formula – Determination of melamine and cyanuric acid by liquid chromatography and tandem mass spectrometry (LC-MS/MS)
This document specifies a method for the determination of melamine and cyanuric acid with liquid chromatography in combination with tandem mass spectrometry (LC-MS/MS). The method has been validated in an interlaboratory study via the analysis of spiked samples of milk-based infant formula, soy-based infant formula, milk powder, whole milk, soy drink and milk chocolate ranging […]
ISO/TS 23758 | IDF/RM 251: 2021 – Guidelines for the validation of qualitative screening methods for the detection of residues of veterinary drugs in milk and milk products
This document describes general workflows and protocols for the validation and the verification of qualitative screening tests for the detection of residues of veterinary drugs in liquid milk (raw, pasteurized, UHT and reconstituted milk powders and whey protein extracts) including biological methods. This guideline does not cover the validation of residue analysis by HPLC, UHPLC […]
ISO 14501 | IDF 171: 2021 – Milk and milk powder – Determination of aflatoxin M1 content – Clean-up by immunoaffinity chromatography and determination by high-performance liquid chromatography
This document specifies a method for the determination of aflatoxin M1 content in milk and milk powder. The lowest level of validation is 0,08 µg/kg for whole milk powder, i.e. 0,008 µg/l for reconstituted liquid milk. The limit of detection (LOD) is 0,05 μg/kg for milk powder and 0,005 μg/kg for liquid milk. The limit […]
IDF Factsheet 7/2019 Bioprotection
Food preservation has been a key concern since the earliest days of humanity. Among the numerous empirical processes that have been developed and passed down, fermentation is one of the oldest preservation techniques and still widely used in various food matrices. This factsheet gives information on dairy and bioprotection.
Use of wood in cheese ripening
In some countries the use of wooden vats or the practice of ripening cheese blocks/loaves on wooden shelves is considered critical in moisture exchange and in defining the final texture and flavour of such cheeses.
Bulletin of the IDF N° 508/2021: Guidance on application of EC JRC Certified Reference Material for somatic cell counting in milk
This paper provides relevant guidance on how to apply this material for method performance verification of both the microscopic reference method and routine methods, for verification and possibly required adjustment of calibration settings of routine methods, for assigning reference values to secondary reference materials and for use in proficiency testing.
Bulletin of the IDF N° 504/2020: New applications of MIR spectrometry: Quality assurance practices with new parameters in raw milk analysis
Traditionally applied for quantitative determination of major components of milk, MIR Filter apparatus techniques have been used for a long time. Recently, Fourier-transform infrared spectroscopy (FTIR) collects high-spectral-resolution data over a wide spectral range. Thanks to additional prediction models developed by researchers and instrument manufacturers, FT-IR spectra can be used beyond quantitative determination of major […]
